2012年10月25日 · What is the maximum size of HTTP packets? I am interested in the size of the response to an HTTP GET request (Not this! This question is about the request size). Is there a size at all? If I download a 1GiB file, does that end up as just 1 HTTP GET request?

2020年1月22日 · The HTTP specification recommends 8000 octets in section 4.1: It is RECOMMENDED that all senders and recipients support, at a minimum, URIs with lengths of 8000 octets in protocol elements. Note that this implies some structures and on-wire representations (for example, the request line in HTTP/1.1) will necessarily be larger in some …

2009年9月4日 · I would suggest you use a full packet sniffer like wireshark. You would love it :) Get it here: http://www.wireshark.org/

2010年6月14日 · The HTTP specification doesn't impose a specific size limit for posts. They will usually be limited by either the web server or the programming technology used to process the form submission.

2025年3月13日 · HTTP Extensions for Web Distributed Authoring and Versioning (WebDAV) These extensions of the Web, as well as CardDAV and CalDAV, are out-of-scope for HTTP on the Web. Modern APIs for application are defines using the RESTful pattern nowadays.

2019年8月5日 · Many web performance experts recommend putting all critical resources in the first 14 KB of your web page. This is based on a bit of understanding of TCP which underlies each HTTP connection – at least for now until HTTP/3 and QUIC come along. But is it really true?

Packet size is defined by the OS (in general), and is related to buffers, amount of data provided by the application, etc. Many strategies can be used to achieve maximum performance, and sometimes send smaller packets can be faster than waiting to create a bigger packet.

2022年10月30日 · method with the HTTPS server, we get a packet length of around 16 KB (i.e. much larger than the size of a single TCP/IP packet and much larger than the size of a packet in our packet pool).

2014年1月28日 · Assume a common MTU of 1500 bytes packet size ; the HTTPS protocol overhead will still leave at least 1400 bytes effective payload data size, therefore in max 6-7% increase in bandwidth. CPU Load: The most computational expensive part is the public key exchange, after which a relatively efficient symmetric cypher is used. Most quotes suggest ...

2022年3月28日 · The absolute limitation on TCP packet size is 64K (65535 bytes), but in practicality this is far larger than the size of any packet you will see, because the lower layers (e.g. ethernet) have lower packet sizes.
